Calculate the mean free path and the binary number of collisions per liter per second between HI molecules at 300 K and 1.00 atm. The collision diameter of the HI molecules may be taken to be 5.10 A. Assume ideal-gas behavior.
Concentrations of aerosol constituents are sometimes expressed as ppb (mole fraction) to enable comparison with gaseous concentrations expressed in ppb. The unit ppb (mole fraction) is evaluated as RT x concentration of aerosol constituent in nano..
A certain rifle bullet has a mass of 9.81 g. Calculate the de Broglie wavelength of the bullet traveling at 1433 miles per hour.
A creature moves at a speed of 3.20 furlongs per fortnight (not a very common unit of speed). Given that 1 furlong = 220 yards and 1 fortnight = 14 days
The infrared spectrum of a putative metal hydride complex exhibited an intense feature at 1910 cm-1 that was thought to be due to iridium-hydrogen stretching (Ir-1H). An isotopic substitution experiment aimed at confirming the origin of this spect..
How many moles of photons with a frequency of 1.22e14 hz are necessary to produce
Considering the electron configuration of aluminum, 1s2s^22p^63s^23p^1, which of the following represents the valence electrons only:
an empty aerosol can at 25 degree calcius still contains gas at 1.00 atmosphere pressure. if an empty can is thrown into a 475 degree calcius fire, what is the final pressure of the heated can?
A 1.00-L gas sample at 100.°C and 589 torr contains 50.0% helium and 50.0% xenon by mass. What are the partial pressures of the individual gases?
A 0.062 M aqueous sample of species y was analyzed by atomic absorption spectroscopy at 525 nm and in a 1.00-cm cell and yielded a %T value of 70.19 % . Calculate the molar absorptivity of species y.
How many grams of sodium azide are needed to provide sufficient nitrogen gas to fill a 35.0x35.0x25.0 cm bag to a pressure of 1.20 atm at 26 degress C.
a 0.336 gram sample of sodium carbonate required 28.6ml of a sulfuric acid solution to reach the endpoint for the reaction Na2CO3 +
The pressure is changed to 8.75 atm and the gas is cooled to 15 C. Calculate the new volume of the gas using the ideal gas equation.
